Tools required : T55 male socket and two 18 mm wrenches, or one18 mm and one 3/4" wrench

( NOTE: just checked, all the prices still apply ! )
( another NOTE: lube up inside and outside of the poly inserts with white lithium grease or you will have squeaking and groaning after a short time )

Don't know about front adjustables.
